High-Temperature Flexible Duct Hose for Fumes

Flexible
Compatible Clamps: Worm-Drive Clamps
Color: Black or Red
Temperature Range: Neoprene Coated: -65° to 300° F; Silicone Coated: -75° to 500° F

Combining the heat resistance of metal with the flexibility of fabric, this fiberglass hose has a special coating that stands up to high temperatures. Hose is for use with smoke, water-based paint fumes, and welding fumes.

Neoprene-coated hose meets UL 94 HB and UL 94 V-0 for flame retardance and can also handle sparks.

Silicone-coated hose handles a wider temperature range than neoprene-coated hose.

Hose with cuffed ends has finished edges for easy attachment to duct hose connectors.

Warning: Hose should not be used for applications that generate a static charge.

Insulated Bend-and-Stay Metal Duct Hose for Air

Very Flexible
Compatible Clamps: Worm-Drive Clamps
Color: Silver
Temperature Range: -100° to 435° F

Bend this hose into position in heating and cooling applications where it’s important to maintain the temperature of the air inside the hose. Unlike fabric duct hose, this lightweight aluminum hose holds its shape once it’s curved around corners. It’s insulated with a layer of fiberglass, so it keeps air flowing through at a consistent temperature even when it’s routed through hot or cold spaces. The metalized film cover seals out moisture, protecting the insulation underneath.

This hose is not meant to be continuously flexed. Lengths beyond 6 ft. may need support.
